Subject: [PATCH] Update canvas_item_shader.rst

I tested it and it is upper left, not lower left.
This is the CanvasItem shader I used to test it:


shader_type canvas_item;

void fragment() {

	if(distance(FRAGCOORD.xy, vec2(40, 40)) < 30.0)
		COLOR = vec4(1,0,0,1);
	else
		COLOR = vec4(0,0,0,1);
}
